birdy Posted November 22, 2017 Report Share Posted November 22, 2017 (edited) Ride around whilst holding the front brake on, then when hot pour cold water on the disc and pads, it cleans up the pads and disc. I do it from time to time to keep brakes sharp. Cheers Edited November 22, 2017 by birdy Quote Link to comment Share on other sites More sharing options...

cleanorbust Posted November 22, 2017 Report Share Posted November 22, 2017 Sure you've bled the system absolutely thoroughly? Any air at all left in brake line will give a deficient brake. Quote Link to comment Share on other sites More sharing options...

scifi Posted November 22, 2017 Report Share Posted November 22, 2017 (edited) Many years ago, before front wheelies became popular, we used to take our bikes for scruitineering with the brake adjusted to lock the front wheel. After being scruitinised, we would loosen the brake so that it would not bind... The reason being that we did not want to cause a front wheel slide in the sections, if we grabbed the brake too quickly. But I suppose you now want to do front wheel pivot turns..!

carl ekblom Posted November 22, 2017 Report Share Posted November 22, 2017 Gold Fren was no success for me. Brake disc must be very clean. I use aceton to degrease and Red Galfer brake pads as I think they are the best /Carl 1 Quote Link to comment Share on other sites More sharing options...

heffergm Posted November 22, 2017 Report Share Posted November 22, 2017 If you've gotten something on the disc, like brake fluid or grease, you're just destroying all the pads you put back on that disc. Make sure you clean the disc with brake cleaner before fitting new ones. Quote Link to comment Share on other sites More sharing options...
dan williams Posted November 22, 2017 Report Share Posted November 22, 2017 Heffergm is correct. If your disk is contaminated then it will contaminate every pad you put in. The disk must be absolutely clean of oils. I've cleaned contaminated pads by heating out of the caliper with a propane torch. The front calipers on Betas seem to be rather mellow compared to TRS and Vertigo units. Could just be the way they are set up. It doesn't take much of an air bubble to soften hydraulics and other things like hose flex will have a similar effect. Ron Commo used to have custom thin stainless steel brake lines made for his Betas to sharpen up his brakes Quote Link to comment Share on other sites More sharing options...
242 Posted November 22, 2017 Author Report Share Posted November 22, 2017 Thanks but the lever is hard not spungy like there’s air in the system think it must be the disc and pads contaminated Quote Link to comment Share on other sites More sharing options...
dan williams Posted November 22, 2017 Report Share Posted November 22, 2017 Agreed ,if the lever is not spongy contamination is most likely culprit. Quote Link to comment Share on other sites More sharing options...
